Aspects of the reproductive biology, including mating, vitellogenesis, and development accessory glands, both male female Phormia regina were investigated. Non-diapausing adults showed changes in ovaries, plus fat body glands sexes, that correlated with major events. The these structures influenced by diet diapause-inducing conditions. importance protein non-diapausing, cyclorrhaphous females is well documented; consequently, emphasis has been placed on significance non-diapausing males its...

The house fly, Musca domestica, serves as a mechanical vector for numerous pathogens, posing significant risk to human and animal health. More than two decades ago, the domestica salivary gland hypertrophy virus (MdSGHV) was discovered, infecting both males females flies disrupting mating reproductive process. While MdSGHV can infect various tissues, its primary replication site is fly gland. It well established that arthropod glands play an important role not only in acquiring food but also...

The intake of protein and sucrose by male female apple maggot flies was highest during week 1, decreased slightly weeks 2 3, remained at a lower level until day 45 (= end experiment). These changes were closely associated with maturation the reproductive system in adult behavior. Females consumed greater amounts more than males, reflecting their need for egg production to support biomass. Also, there significant quantitative differences between wild laboratory-cultured food intake, arrival...

The face fly, Musca autumnalis De Geer, exhibited a true imaginal facultative diapause characterized by fat hypertrophy in both sexes and cessation of ovarian development females. Adults were sensitive responsive. Temperature photoperiod influenced induction. Continuous light high temperature (83°F) prevented diapause. Percent flies diapausing increased as was lowered shortened. Almost all diapaused when subjected to continuous dark at 65°F. Diapausing failed feed on cow's blood mate. became...

Reproductive behavior of both sexes the apple maggot was shown to be correlated with ovarian and accessory gland development, changes in fat body. A protein free diet resulted a drastic reduction development after day 5 females. Spermatogenesis independent little required for male development. Mating apparently not affected by diet.

This study showed that in adult Drosophila melanogaster, the type of sugar—either present within crop lumen or bathing solution crop—had no effect on muscle contraction. What is important, however, volume lumen. Electrophysiological recordings demonstrated exogenous applications serotonin muscles increases both amplitude and frequency contraction rate, while adipokinetic hormone mainly enhances frequency. Conversely, octopamine virtually silenced overall activity. The reports for first time...

Antibody to the dipteran myosuppressin peptide, dromyosuppressin, TDVDHVFLRFamide, stained cells and fibers in brain, optic lobes, subesophageal ganglion, thoracico-abdominal ganglion of blow fly, Phormia regina (Meigen). Dromyosuppressin-like immunoreactive were detected cardiac recurrent nerve, hypocerebral ganglion/corpora cardiaca complex, crop duct, crop. In order explore mechanisms involved regulating movement, we established an vitro bioassay. The basal rate movement was 50.8 +/- 1.5...

Male house flies, Musca domestica L., perform a stereotyped courtship ritual which includes the following elements : orientation, landing, wing-out, leg-up, head lapping, touching, boxing, backing, genital contact, and copulation. Although female plays minor role in courtship, she does control its success by either extruding or failing to extrude her ovipositor. We propose that primary function of fly is appeasement. The wing-out leg-up prevent escape kicking rejection courtship. remaining...

ORF virus (Poxviridae) is the causative agent of contagious ecthyma (soremouth), a disease primarily affecting sheep and goats worldwide, but also humans exposed to disease-ridden animals. Pathogens are shed with scabs, infection mainly occurs by direct contact. Although relatively benign self-limiting, morbidity rate high in livestock subsequent significant financial economic impact. The aim study was experimentally investigate potential for housefly, Musca domestica, act as mechanical...
